Tested, validated, safe – so that your filters deliver what the cover sheet promises

Our particulate filter tests ensure that your filters function optimally and comply with the applicable standards or specifications. 
Our services include, among others:

Differential pressure measurements
Measurement of the pressure difference to ensure the filter is functioning properly.

Particle separation efficiency measurements based on different aerosols 
Precise determination of your filter’s separation efficiency under various conditions.

Dust Holding Capacity (DHC) testing 
Measurement of the filter’s ability to collect dust.

Verification of the functionality of hypoallergenic bedding
Special tests to confirm the effectiveness of products for allergy sufferers.

Use of various test dusts and aerosols
Use of test dusts and aerosols in size ranges from 20 nm to 20 µm to ensure the effectiveness of the filters under demanding conditions.

Laboratory aging through climate cycling tests, IPA discharge, or dust loading
Conducting tests according to various specifications to assess the durability of the filter elements and their performance values during simulated aging.
